DeadAir's wording: cut the dead air (#172)

The switch, the button's tooltip, the toasts and the time saved now say
what the name already pictures, the dead air cut, instead of explaining
it as silences shortened each time. The caption says the voice keeps its
own pace, which is the part people doubt, and names the shows to leave
out: stories whose pauses are part of the telling.
